Are white lines normal on dark scenes ?

You'll have to be more specific about these "white lines" to get much of an educated response, but I'd say that most definitely NO is the answer. Since the connection isn't the culprit, borrow another DVD player from a friend with the same disc and try that. If the white lines still appear, you'll know that your TV is to blame. Chances are that your video settings are incorrect (most people's are WAY off), so you could start with that. If not, get a new TV if it bothers you too much. Cheers!
